I don't think RIO(Argyle) will be interested as it's too small for them, others might but imo it's probably only mainly the T5 aluvials that adjoin POZ leases that would be clearly economic.
The government had it up for grabs for a long time and no one was keen to take it on with the existing environmental liabilities.
Maybe POZ is going slow, give the potential bonanza grades in the gpr defined alluvial traps adjoining.
